Imagine spending your nights sleeping thousands of times, each time for only four seconds. Does it sound like a nightmare? 1.
Like other penguins, chinstrap penguins spend much of their time in the water. But when the time comes to raise their young, they return to land to build nests and lay eggs. Usually, one parent guards the nest while the other hunts for food. The “guarding parent” must always keep an alert(警惕的)lookout. 2. Getting a good night's sleep can be deadly for the young, but it's hard to stay alert for 20 hours a day. Chinstrap penguins have found an unusual way to solve the problem.
In a new study, scientists report that chinstrap penguins take thousands of “microsleeps” every day. 3. By taking over 10,000 microsleeps a day, the penguins get a total of about 11 hours of sleep a day.
Niels Rattenborg is one of the scientists. He says the penguins are always “blinking” their eyes. 4. Dr Rattenborg says it's amazing how they can keep guarding their nests, eggs, and babies while sleeping like this.
5. Do these microsleeps help the penguins feel truly rested, or just help them stay alive? Do they sleep this way only when they have babies, or at other times too? More studies are needed to learn about these birds that cannot fly.
A. But scientists still have questions
B. Each sleep lasts only about four seconds
C. They do this around the clock for several weeks at a time
D. Well, that's exactly how chinstrap penguin parents sleep
E. Scientists have found that other penguins also have similar sleeping habit
